Abstract
Cerebral angiography (CAG) performed on 5 cases of hemiplegia accompanied with mild cloudiness of consciousnes revealed obstruction of the middle cerebral artery.
CAG on one of the 5 cases showed marked arteriosclerosis with incomplete obstruction of the anterior cerebral artery. The general condition as well as the clinical symptoms gradually became aggravated together with hemiplegia, and eventually, death followed. Autopsy revealed obstruction consistent with the CAG finding. On study of the appearance of the obstructed end of the artery in each of the 5 cases, sharp demarcation was noted in 3 cases but 2 cases presented a floccular appearance, which was suggestive of soft thrombi.
Repeated CAG in 1 to 3 months revealed another patency in the 2 cases in which the obstructed end showed a floccular appearance. Their clinical symtcnis were well improved as compared with those of the other cases.
Another one of these cases was a 24-year-old female, who developed the obstruction on the day when oral administration of luteal follicular hormone was started. It is indeterminable whether this drug has caused thrombosis.
